How do you calculate the value of a resistor?

Selection of a resistor through a quick circuit analysis.

  • Checking the parameters like nominal value,tolerance,power rating,voltage drop,current through it,power dissipation by it and other properties,if required.
  • Calculating the power requirement of the desired resistor.
  • Checking if the exact value of that resistor is available.

    1MΩ = 1MO

  • 470KΩ = 0M47 or 470K
  • 47KΩ = 47K
  • 4.7KΩ = 4K7
  • 1.0KΩ = 1K0
  • 0.47Ω = 0R47 or R47
  • 1.0Ω = 1R0
  • 47Ω = 47R

    Hartley– The resonant circuit is a tapped inductor or two inductors and one capacitor.

  • Hartley– The resonant circuit is a tapped inductor or two inductors and one capacitor.
  • Reduce ringing to limit the peak voltage on a switching transistor or rectifying diode and to reduce EMI by reducing emissions and lower- ing their frequency.
